In terms of performance: 1.The density of zirconia ceramics is twice that of alumina ceramics, the bulk density of zirconia is 6.05g/cm3, while that of alumina is only 3.7g/cm3. So zirconia has better compressive properties in comparison. 2.The toughness of zirconia ceramics is 4 times that of alumina ceramics. The toughness of the zirconia ceramic is excellent, which overcomes the inherent brittleness of the ceramic itself, has higher wear resistance, and greatly extends the service life of the product. 3.Zirconia parts with higher surface finish. After grinding and processing of two materials, zirconia has a higher surface finish, and the roughness can reach about Ra0.02. The surface is mirror-like, very smooth, and has a smaller coefficient of friction. But alumina roughness is about Ra0.2~Ra0.4. 4.Zirconia ceramics have excellent thermal insulation, and its thermal conductivity is less than one-tenth of the thermal conductivity of other ceramics. In terms of price: The price of alumina is lower than that of zirconia. One of the reasons is the cost of the raw material, another reason is the high processing cost of zirconia ceramics. In terms of applications: 1.Alumina ceramic could withstand higher temperature, application in industry furnace. 2.As the wear resistance for zirconia is much better, it is frequently used as mortar and pestles, grinding jars and grinding media, bearing balls and ceramic parts in valves and pumps. 3.Zirconia has better corrosion resistance. Zirconia could survive longer in highly corrosive environment and is considered better material in chemistry laboratories. So Zirconia ceramics are suitable for applications in high-load, high-strength, and chemically corrosive environments, while alumina ceramics are suitable for applications with low loads, high temperatures, and heat dissipation.

The story of advanced ceramics is an interesting story of how the creation of technical ceramics and the discovery of the potential for various uses of technical ceramics can influence the development of many different industries that use advanced ceramics in their everyday operations. What’s more, it is an account of how further refinement of a certain material can lead to technical ceramics being used for numerous interesting and unusual purposes. So, let’s see about the beginning of advanced ceramics and witness how long technical ceramics manufacturers have come from the early days. What is the history of technical ceramics? The history of technical ceramics can be divided into three distinct periods, and it all begins with earthenware. It was several thousand years ago that humans first learned to make earthenware vessels through kneading and forming clay. However, the first major breakthroughs concerning ceramics were made in China. Ceramics in China It was in China that the first advancements in working with ceramics were made, as well as the various uses for earthenware porcelian and vessels. For example, the method called "Chaishao", where clay vessels were fired at temperatures that ranged from 1,000 to 1,400℃ while surrounded by piles of wood was invented in China. Electrical technology The invention of the electric light bulb by Thomas Edison, as well as the invention of the telephone by Alexander Graham Bell, noted the beginning of a new era – the era of electricity. Up to that point, ceramics were only used as vessels. However, ceramics would get a completely new role. Their insulative capabilities made them a far better alternative to paper or wood, as well as the fact that they were far less affected by environmental factors such as humidity and temperature. This made ceramics extremely reliable. Since then, ceramics became widespread as insulators in many different areas, from household products to power lines, and it is technician ceramics that allowed people to easily use electricity. Electro-ceramics The inventions of the radio, the television, as well as the transistor in the 20th century marked the beginning of electronics. This entire era relied on technical ceramics from the very beginning and the vacuum tubes that employed ceramic materials. Since then, technical ceramics have been used in many different ways in the electronics industry, the two most notable being: Wireless equipment – Only technical ceramics are able to provide high-signal output due to their properties. Semiconductors – The core component of electronics, semiconductors would not be possible without technical ceramics. Technical ceramics have also managed to reduce the size of inductors and capacitors. What’s more, technical ceramics are constantly evolving, and can now even boast incredible magnetic and dielectric properties. It is this possibility for improvement that makes technical ceramics one of the most versatile and future-proof materials today. Who is the leading technical ceramics manufacturer in the China?
